IIIc. SWD Location Forecasts - Central

This tool provides an automated daily update of SWD degree-days (see reference table) for selected locations in Central and Midwestern states. This provides a convenient at-a-glance summary of SWD development for the current year and relative to previous years and 30-year normals. For example, say that a given location is "12 days ahead of last year" and "22 days ahead of 2 years ago", and "9 days ahead of normal". This would mean that the current year can expect to produce populations that develop much sooner than expected, with an associated increase in relative risk to early and mid season fruit crops.

Click on the degree- day totals to run the full DD model for that location to get details including a forecast into the next 7 days using a National Weather Service forecast and beyond using 30-year normals.
